Step one — before anything else:Mix half a teaspoon of high quality matcha powder with 100ml of warm water. Swish gently around the mouth for sixty seconds, making sure it reaches every surface. Spit. Do not rinse after. Matcha contains epigallocatechin gallate — a natural compound that has been shown to actively suppress Streptococcus mutans, the primary bacteria responsible for decay and gum inflammation. This is why Japanese people have used green tea for oral health for over a thousand years. It is not tradition for tradition's sake. It is effective.
Step two:
Using a copper tongue scraper (copper has natural antimicrobial properties), scrape the tongue from back to front with seven firm but gentle strokes. This removes the bacterial biofilm that accumulates overnight. A plastic scraper works, but copper is what we use in Japan.
Step three:
Oil pull with one tablespoon of black sesame oil for three to five minutes. Sesame oil contains sesaminol, which has documented antibacterial properties specific to the oral environment. Spit into the bin. Rinse with warm water only.
Step four:
Only now — brush normally.
This entire ritual takes under twelve minutes.
